In a large pot, heat some oil over medium heat. Cook the chicken until browned and cooked through, then remove and shred.
In the same pot, add garlic and diced vegetables. Sauté until softened.
Cooking
Add chicken broth, Italian seasoning, and tortellini. Bring to a boil.
Reduce heat and simmer until tortellini is cooked, about 5-7 minutes.
Stir in the shredded chicken and spinach (if using). Optional: add cream for a richer soup.
Season with salt and pepper to taste. Serve warm.
Notes
Serve with fresh herbs or grated Parmesan cheese for added flavor. Pair with crusty bread or a salad for a complete meal. Leftovers can be stored in an airtight container for 3-4 days in the refrigerator or frozen for 2-3 months.
